The largest-ever scaffold was built in 2008 to enable major renovation work at the Hong Kong Coliseum in 2008.   It was quite spectacular.  The scaffold was built beneath the entire ceiling, which measures about 95m x 95m, and since the coliseum has no columns, the scaffold was suspended by cables from the ceiling.   It was double-layered: the lower layer was to facilitate work on lighting and sound equipment and the upper for air-conditioning work.

The whole scaffold was divided into 4 zones.  It took 10 days to erect each zone and 7 to dismantle it.   A total of 40,000 bamboo poles were used for the lower layer alone.
